Assembled in the UK we offer a wide range of extension leads from 13 Pin, 8 Pin and 7 Pin. All leads supply lighting functionality to trailers. If you don't find what you need, please contact the sales team with your specification.  All assemblies are ISO compliant.

We supply 8 and 10 way electrical junction boxes, which give you a waterproof connection and allow all of your road lighting to be wired.

Towbar testers are perfect for checking all electrical circuits are working correctly after installation and before towing.

We stock a range of relays used in vehicle towing electrics

Audible / Tell-Tale Relay -  Audible relays buzz in time with the vehicle's indicators when connected. It is a legal requirement to have either a visual or audible monitor fitted so the driver is aware that the indicators are working on a trailer or caravan.

Bypass Relays - Bypass relays are used to switch trailer and caravan lights on and off.  The relay is connected to the lighting circuit and only draws a small current meaning it cannot be detected by bulb failure sensors in most vehicles.  All bypass relays can be powered using either the battery or fuse box. A fused 12v power supply required for installations.

Electronic Bypass Relays - Exclusive to Maypole, these relays are compatible with LED lamps on a trailer. Only for 12v vehicles and easier to replace if the current relay is faulty.
